Connection Problems
A typical FWSM is depicted in Figure 4-5, in which MSFC is situated on the outside interface of the FWSM.
Figure 4-5. A Typical FWSM Deployment
As shown in Figure 4-5, VLAN 10 is sitting on the inside, and VLAN 50 is the SVI interface on MSFC. The outside interface of the FWSM is configured to be part of VLAN 30 on the switch. Hence, this interface VLAN 30 on the MSFC is used by the FWSM to communicate with MSFC and any other VLANs configured on the MSFC.
This section examines the following two topics in detail based on Figure 4-5.
